The Tech 

If you want to know our verdict on the irons, scroll to the bottom, but if you want to know the tech detail straight from Mizuno, this is the section for you.

When it comes to the tech, the JPX925 irons feature a CORTECH design with a Contour Ellipse Face, a multi-thickness face profile that is 30% thinner than its predecessor. This design enhances ball speed and ensures maximum speed retention throughout the impact zone. In addition, the multi-material construction, incorporating tungsten weighting in the 4-7 irons, positions the weight low to facilitate a higher launch and lower sweet spot. This design produces a steeper landing angle, optimising playability and control.  

The JPX925 Hot Metal Irons also benefit from the inclusion of Chromoly 4140M, a high-strength material known for its excellent strength-to-weight ratio and malleability. This allows for a high-strength face with a pliable hosel for precise fitting. The seamless one-piece cup face geometry, with thinned areas around the perimeter, helps to maximise the rebound area for unparalleled ball speed across the entire face. 

Additionally, a variable sole thickness enhances the overall face flex area, contributing to increased CORAREA (Coefficient of Restitution). This, combined with a balanced stability frame, improves control while maintaining forgiveness, producing a tour-preferred vibration and sound. Mizuno’s Harmonic Impact Technology, featuring meticulously fine-tuned head geometry, delivers an ideal feel and feedback at impact. Meanwhile, Acoustic Sound Ribs ensure precisely calibrated vibration patterns for a solid, explosive impact sound. 

The big question is, with similar tech, how do they differ? The JPX925 Hot Metal offers maximum speed and consistency with the CORTECH Design and Contour Ellipse face for unparalleled distance control. The JPX925 Hot Metal Pro combines the same advanced technology with a slimmer, more refined profile for golfers seeking a compact design. Lastly, the JPX925 Hot Metal High Launch delivers max launch and spin, featuring the same cutting-edge technology in a larger footprint. 

“The new Hot Metal Iron family introduces a multi-material design, strategically incorporating tungsten into our Nickel Chromoly designs, enhancing the renowned Hot Metal distance with impressive height and spin. With three distinct models to choose from, each offering extensive custom fitting options, we uphold the quality and craftsmanship Mizuno is renowned for. We are dedicated to continually setting new standards of performance in the industry.” 

“With the JPX line, we are pushing the boundaries of golf club engineering,” said David Llewellyn, Director of R&D.
